SOOT-BLOWERJHEADEB.

To all whom it may concern: 7

Be it known that I, WILLIAM F. SELLERs, a citizen of the United States of America, and a resident of Brandywine Hundred, Delaware, have invented a certain new and useful Improvement in'Soot-Blower Headers, of which the following is a true and being had to the accompanylng drawings, which form a part thereof. r 1

My present invention consists of novel means for connecting metallic pipes to metal and the tubes are subjected to high temperatures, and the tubes do and the pipes do not contain at all times, a heat absorbing liquid. The primary object of the invention is to provide an effective heat conducting connection between the said pipes and tubes whereby the heat absorbing effect of the liquid in the tubes operates to keepthe pipes from reaching undesirably high temperatures. My invention is especially devised and adapted for use as a means for protecting the 800i; blower pipes located in the furnace chamber of a water tube boiler against the temperatures to which they are subjected by connecting them in good heat conducting relation with the water tubes of the boiler.

The various features of novelty which characterize my invention arepointed out with particularity in the I claims annexed hereto and forming a part of this specification.

For a better understanding of the invention,

however, and the advantages possessed by'it, reference should be had to-theaccompanying" drawings and descriptive matter in which I have illustrated and described a preferred embodiment of my invention.

cleaning fluid as air or steam into the inter tube space, ordinarily in directions parallel to the length of, the tubes. The blower pipes; C in each baflle are connected to a header or supply main pipe C, which is located beneath the lower row of water tubes and extends transversely to the latter, and directly across the path of the products ofcombustion.

The pipes C are connected to the water tubes A above them by metallic clamps D, and are placed in good heat conducting relation with the tubes A by means of the clamps and metallic saddle blocks or spacers Finterposed between each pipe 0 and some or all of the tubes A in the lower row ofv the boiler water 7 tubes. As shown, each clam-p D comprises two opposed similar parts d. Each part d comprises a body portion extending between anadjacent pair of tubes A and is provided at its upper end with oppositely projecting horns or arms D which extend over the two tubes between which the body portion of the. clamping part extends. At its lower end each clamping part 01 is formed with a curved seat D? shaped to fit against the adjacent side of the pipe C. Each clamping part is also formed between the ends With a lug or shoulder D The two clamping parts of each secured together by. means of a bolt E which passes between the clamp are clamping upper side of the pipe C and the line of contact between theflopposing shoulders D of the two clamping parts d. Each saddle block or spacing partIF, in the preferred construction illustrated, is formed with a cylindrical seat F in its upper side shaped to {it against the under side of the correspondmg water tube A, and is formed at its under.

side with a cylindrical to the seat F and shaped to receive the upseat F transverse per side of the corresponding soot blower pipe C.

With the construction described and with the partsassembled as shown in the drawing the tightening up of the bolt Eof each clamp causes eachfof the clamping parts (1 connected thereby to fulcrum about the line of contact between the opposing shoulders i'do D as an axis and thereby grip the COII'G':

sponding pipe G between the opposing seats D of the clamp. These seats are so shaped and the parts are so proportioned that the gripping action .of the seats tends to cam-or lift the pipe O upward and thus put the saddle blocks F between the tubes A and pipes C under compression. The contact surfaces of the saddle blocks and the pipes G and tubes A, and of the clamps D and the tubes A and pipes O are made relatively large so that the pipes C are thus not only well secured mechanically to the water tubes but are in good heat transferring relation with the latter. The pipes C, as well as the saddle blocks F and the clamps D are therefore maintained at a temperature practically no higher than that of the water in the water tubes A, although the temperature of the products of combustion sweeping over the pipes C and clamps D is much higher. By the use of my invention a serious practical difficulty heretofore experienced with boiler soot blower arrangements of the general character illustrated is avoided. The soot blower pipes C proper may be sufficiently protected against thetemperature to which they are subjected by embedding their upper portions in the bafile walls and by covering the lower portions of these pipes with a suitable refractory heat I but it has not been found practically possible to satisfactorily protect the main or header pipes C by such a covering.

hile in accordance with the provisions of the statutes I have illustrated and described the best form of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form ofmy invention without departing from its spirit, and that some features of my invention may sometimes be used to advantage without a corresponding use of other features of the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a water tube boiler, the combination with the water tubes, of a pipe or header and metallic spacers and clamps having extended surfaces in contact with both the water tubes and header.

2. In a water tube boiler, the combination with the water tubes, of a pipe or header, metallic spacers or saddle blocks interposed between the pipe or header and the water tubes and having extended cylindrical segment surfaces in contact with both the headers and tubes, and clamps holding the tubes and headers against the interposed saddle blocks.

3. In a water tube boiler, the combination insulating covering G,

with the water tubes, of blower piping and metallic parts connecting, and having extended contact surfaces in gripping contact with said tubes and pipe.

4. I11 a water tube boiler the combination with the water tubes of a blower pipe or header extending transversely of the bank of tubes, metallic saddle blocks interspaced between the pipes and adjacent tubes and each formed with'a cylindrical seat for the pipe and with a transverse cylindrical seat for the adjacent water tube, and metallic clamping means extending between the pipe and adjacent water tubes and serving to clamp the pipeand watertubes in the corresponding saddle block seats. 7

5. In a Water tube boiler the combination with the water tubes of a blower pipe or header extending transversely of the Water tubes, and clamps for connecting the pipe to adjacent water tubes, each clamp comprising cooperating parts each of which has a portion extending between the adjacent pair of water tubes with projections at one end of said portion adapted to engage the said pair of tubes, and provided at its opposite end with a surface adapted to engage the pipe and provided between its ends with a shoul- -der adapted to abut against the corresponding shoulder of the cooperating clamping part, and clamping means acting on the cooperating clamp parts and tending to draw the pipe engaging surfaces of the latter together, said surfaces being shaped to force the pipe toward the tubes as the surfaces approach one another.

6. In a water tube boiler the combination with the water tubes of a blower pipe or header extending transversely of the water tubes, and clamps for connecting the pipe to adjacent water tubes, each clamp comprising cooperating parts each of which has a portion extending between the adjacent pair of water tubes with projections at one end of said portion adapted to engage the said pair of tubes, and provided at its opposite end with a surface adapted to engage the pipe and provided between itsends with a shoulder adapted to abut against the corresponding shoulder of the cooperating clamping part and a clamping bolt for drawing the cooperating clamp parts together passing between the pipe and the said shoulders; the said surfaces being shaped to force the pipe toward the clamping bolt is tightened.
